Soldering Techniques

Soldering is the process of joining metallic surfaces with a metal or metallic alloy. The most commonly used soldering lead is an alloy of tin and lead.

It is of prime importance to have good quality soldered joints in the assembling of electronic projects and circuits. The beginner, particularly, must learn to solder correctly to achieve satisfaction and success.

Components are supported by a variety of methods, and connections rely on the soldered joint. The solder is not meant to provide mechanical support.

Solder. Solder is an alloy of tin and lead that melts at a low temperature. Soldering creates a continuous intimate contact between the solder and the metal surfaces. A good joint should be made electrically connected and mechanincally sound.

Solder for electronics work is made up of different gauges. Most have a resin core along their length. This resin acts as a flux to remove any oxidized or tarnished metal surface that prevents positive adhesion of lead, resulting in a poor joint. It is ipportant to heat thoroughly the activated resin during soldering to ensure the complete decomposition of the activators: otherwise, they remain corrosive at normal temperature.
